First if I not mistaken jackpot is hit equal to the percentage on how much they wagered, 15 bits can hit 0.5 btc, I would assume thst you have got pretty huge amount of jackpot stored on the site. Second, I wondering too how can with 15bits can get 0.5 btc? Usually 0.01 btc can get all the jackpot and with 15 bits, it should be 10-20%. So how is it possible to have this really big payout?
